I’m no breeding expert and I’m also not an RID/RIDSH guru either, but per your original post, it sounds like you’d like to produce something that gives the old school, well built and sturdy TB feel. Based on what you said, I’d recommend you stick with Ozzie (All’s Well) as I think the baby would be that nice moving, athletic TB-type get with some substance.
As much as I loved Faith, the RIDSH mare by BFD, she was not the better mover or jumper next to Ozzie. I think you need to clarify what you’d really rather have, 3/4 vs 1/2 bred. I worked with these two when they were young and just coming undersaddle, I’m pretty sure Oz matured over 17hh and Faith was pretty close around 16.3-ish. Their mom was the same TB mare. Good luck, I’m excited for you either way!
